Can I build a portal inside a dungeon or burial chamber?

In Valheim, portals are essential for fast travel across the vast world, but their placement is restricted in certain areas, including dungeons and burial chambers. You cannot build a portal inside a dungeon or burial chamber due to the game''s mechanics. These locations are considered enclosed spaces, and the game prevents players from constructing portals within them to maintain balance and challenge.\n\nTo understand why portals cannot be built in dungeons, it''s important to know how portals work. Portals require a clear, open space to function, and they must be placed on solid ground. Dungeons and burial chambers are underground structures with limited space and no direct access to the surface, making them incompatible with portal placement. Additionally, these areas are designed to be challenging, and allowing portals would undermine the difficulty of navigating and escaping them.\n\nIf you need to fast travel near a dungeon or burial chamber, the best solution is to build a portal outside the entrance. To do this, gather the necessary materials: 20 Fine Wood, 10 Greydwarf Eyes, and 2 Surtling Cores. Fine Wood can be obtained by chopping down birch or oak trees, Greydwarf Eyes drop from Greydwarfs, and Surtling Cores are found in burial chambers or dropped by Surtlings in the Ashlands biome. Once you have the materials, craft a portal at your base and name it. Then, place another portal outside the dungeon entrance with the same name to create a connection.\n\nA practical example of this strategy is when exploring the Black Forest biome, where burial chambers are common. Before entering a burial chamber, set up a portal nearby. This ensures you can quickly return to your base to repair gear, drop off loot, or recover if you die. If you die inside the dungeon, you can respawn at your base, use the portal to return to the dungeon entrance, and retrieve your items without losing progress.\n\nFor experienced players, this approach also works in more dangerous biomes like the Swamp or Mountains. In the Swamp, you can place a portal near Sunken Crypts, and in the Mountains, you can set one up near Frost Caves. This strategy saves time and resources, especially when carrying valuable items or exploring high-risk areas.\n\nOne common challenge is managing inventory space while exploring dungeons. Since you cannot build a portal inside, you must plan ahead. Bring only essential items and leave unnecessary gear at your base. Use the portal outside the dungeon to make multiple trips if needed. This ensures you can maximize your loot while minimizing the risk of losing items.\n\nIn summary, while you cannot build a portal inside a dungeon or burial chamber, you can place one outside the entrance for efficient fast travel. This strategy is crucial for both new and experienced players, as it saves time, reduces risk, and enhances exploration. Always prepare materials for a portal before venturing into a dungeon, and use it to your advantage to maintain progress and safety.\n\nPractical tip: If you''re exploring a new area, consider bringing extra portal materials in case you find multiple dungeons or need to relocate your portal. This flexibility ensures you''re always prepared for unexpected challenges.
